Instrument Is Also Certified For Retrofit In CRJ700,
CRJ900

Rockwell Collins announced Thursday at the 36th Annual Regional
Airlines Association (RAA) Convention in Nashville, TN, that its
AHS-4000 Attitude and Reference Heading System (AHRS) is now
certified on the Bombardier CRJ1000 NextGen aircraft.

The AHS-4000 AHRS features a distinctive solid-state, gyro-based
design that is not subject to magnetic abnormalities associated
with flux valves and eliminates the need to perform compass swings.
The latest generation embedded sensors ensure low power consumption
and high reliability, resulting in a 50 percent improvement in Mean
Time Between Failure (MTBF) compared to previous generation
systems.
